Micro – ROS Servo

CPS presents a guide to setup the communication between Micro – ROS and ROS2 and control multiple servos attached to a PWM/Servo Driver board. Therefor the installation of ROS2, the setup of a Micro – ROS workspace, the establishment of the communication with a custom message and the implementation of third party libraries as well as the usage of two different RTOS system will be described step for step.

By combining the power of Micro ROS Foxy, ESP32 and a PCA9685 board, this project provides a way of controlling multiple servos. The setup has been tested on a Linux Ubuntu 20.04.6 LTS environment, allowing seamless communication and accurate servo positioning. The linked guide give some information about Micro – ROS and walks through the installation of ROS2, the setup of a Micro-ROS workspace, and the establishment of the communication between Micro-ROS and ROS2 using a custom message format called “ServoMessage”. Additionally, the guide covers the implementation of third-party libraries and the usage of two different RTOS systems. The code includes examples of how to use the Micro ROS Foxy framework to send and receive ServoMessages over the ROS2 network to control the attached servos.

  • Micro USB Cable
  • ESP32 Developement Board
  • 2 x 4,7 kΩ resistors 
  • PCA9685 PWM/Servo Board

Abstract

Geometric data of a requested forging is important as a source to estimate feasibility and offer realistic pricing. However, every bigger deviation in such calculation regarding technical viability costs involved companies’ possible revenue. 

To mitigate this issue and support the technologists and sales department an autoencoder (unsupervised learning) with an attached regression model was developed (pre-existing). Nevertheless, this system still needs adaptation/improvement to meet the operational requirements. 

This bachelor thesis proposes a way to implement an optimization process for adjusting the layer structure and possible scaling of a given autoencoder system. The autoencoder itself uses 3D surface data in form of a “.stl” to create a point cloud in x, y, and z. A docker image containing the autoencoder then extracts the most significant 3D features and provides an estimation for feasibility and price. The focus lies on creating a wrapper function to test different hyperparameters in an automated way. Strategies like random search, grid search, and Bayesian optimization will be applied. The results of the optimized framework will be challenged with the pre-existing autoencoder model.

Tentative Work Plan

To achieve our objective, the following concrete tasks will be focused on:

  • Literature research
  • Evaluation of the SOTA / the current model
  • Identification of network / hyperparameter optimization options
  • Model optimization / improvement
  • Evaluation and Testing on new data

Short bio: Franz has already a master degree in metallurgy but seeks additional expertise in data analysis and machine learning, therefore currently revisiting the Montanuniversität Leoben as bachelor student in Industrial Data Science.

Graduated in 2015 he went into the quality management of the domestic steel industry. Working in a laboratory environment within a very dynamic market he quickly noticed the unstoppable tendencies to more and more data driven process planning, monitoring and production itself. Therefore, as of March 2023, he is writing his bachelor thesis at the Chair of Cyber-Physical Systems in cooperation with voestalpine Boehler Aerospace GmbH & Co KG.
